1. A gravimetric measuring system, comprising:
a balance with a weighing chamber surrounded by a plurality of weighing chamber walls;
an electromechanical weighing system enclosed by an adjoining weighing system chamber;
an electronic control apparatus for controlling the weighing system operation according to algorithms stored in a memory of the electronic control apparatus; and
a plurality of functional modules that generate heat during operation and are configured for insertion into module receptacles arranged on at least one of the weighing chamber walls;
wherein the module receptacles comprise:
device-side thermal interface components that are thermally connected to one another and to a central cooling apparatus, and
respective device-side identification interface components,
wherein the functional modules comprise:
module-side thermal interface components that correspond respectively to the device-side thermal interface components and, in an inserted state of the respective functional module, thermally contact the device-side thermal interface component of the respectively associated module receptacle, and
respective module-side identification interface components that correspond respectively to the device-side identification interface components,
wherein the control apparatus is programmed to identify each functional module, inserted into a respective one of the module receptacles, through interaction between the respective device-side and module-side identification interface components and to select one of a plurality of operating routines according to the algorithms stored in the memory of the control apparatus,
wherein at least one of the weighing chamber walls forms a separating element between the weighing chamber and the weighing system chamber that is constructed of spaced posts and struts which form an open-sided lattice-like carrier structure having recesses that form the respective module receptacles, and
wherein the recesses are closed on a side of the weighing system chamber by a fixedly installed end wall and are closed on a side of the weighing chamber either by panels that have no weighing function and are spatially adapted respectively to the recesses, or by the functional modules.
